Shredabull Untamed Review – Does This Fat Burner Work? (2020)

Shredabull Review - Does Project AD's fat burner work?

Welcome to our Shredabull Untamed review, a popular fat burner pill manufactured by Project AD and sold on multiple websites online.

Priced at $48.99 per bottle, Shredabull promises to help you:

  • Incinerate body fat “from every angle”
  • Stabilize appetite and suppress “harmful” cravings
  • Increase energy for maximum performance

Sounds great! But does it really work? And is it free of side effects?

We share our thoughts below – a short summary followed by a more detailed analysis of its ingredient formula.

Shredabull At a Glance

Overall, we weren’t too impressed with this fat burner. Not because it doesn’t work – it does – but because it’s unsafe.

Among the ingredients it has Yohimbine and 2-aminoisophetane, both dangerous substances that can aggravate cardiovascular function.

While you’ll be firing on all cylinders with Shredabull, it’s worth asking whether it comes at the cost of long-term health.


  • Caffeine is great for energy & mental focus
  • Some people like the aggressive effects of multiple stimulants combined


  • Poor serving schedule
  • Some ineffective ingredients
  • A few dangerous stimulants and banned ingredients
  • Missing a better appetite suppressant

How Does Shredabull Work?

AD Shredabull Untamed uses ingredients that are known for activating a so-called ‘thermogenesis’ process. This involves a rise in your body’s core temperature, where the metabolism has to work harder in order for the body to cool itself down.

In addition, Shredabull claims to help suppress appettie with some of its stimulants (e.g. caffeine). While caffeine does suppress appetite to an extent, it’s not the most effective natural option. A better choice is Glucomannan (aka, Konjac Root), a fiber that swells in your stomach upon ingestion, physically making you feel fuller.

Another common question is how long does Shredabull last? The answer is, not very long. Since you’ll be taking only 1 capsule per day, the effects between the doses will wear off and so you won’t be in a continual ‘fat burning mode’. It’s better to use a product with 3-4 daily servings to ensure you’re constantly being topped up with beneficial ingredients.

Shredabull Untamed: The Ingredients

Each capsule of Shredabull supplies you with the following active ingredients:

  • Niacin (10mg)
  • Vitamin B6 (5mg)
  • Neurostim Proprietary Blend (495mg)
  • Incinerate Thermo Complex Proprietary Blend (135mg)
  • Thyrocharge Complex (100mg)
  • Bioperine Black Pepper Extract (5mg)

As you’ve probably noticed, Shredabull Untamed contains two proprietary blends. These are mixtures of ingredients that are shown on the label as a single dose. You aren’t able to see the individual ingredient doses in these blends.

This is an issue as you won’t have any idea whether you’re getting enough of certain ingredients, or perhaps too much.

Apart from that, the ingredients themselves don’t look to convincing. There are a few concerning inclusions in there, the most notable ones being Yohimbine and 2-aminoisoheptane.

See for yourself:

1. Niacin

Niacin keeps finding its way into fat burner supplements for some reason unknown to us.

This nutrient, also known as vitamin B3, can actually make it harder for you to lose weight when supplemented.

B3 is known to aggravate insulin resistance, a condition where your body has high blood sugar levels and starts storing more and more fat, while being unable to get rid of the existing body fat tissue.

There’s no real reason to supplement this vitamin as plenty of foods already have it. The only known benefit is improved cholesterol levels. Then again, there are plenty of healthier ways to achieve that.

2. Vitamin B6

Vitamin B6, unlike its cousin B3, doesn’t give you insulin resistance. It actually has a number of small benefits for our body and can be beneficial if you’re a vegan.

It plays a role in homocysteine metabolism, a nasty chemical that can cause plaque to build up within your artery walls. While this doesn’t have much to do with weight loss, it’s a good general health ingredient.

3. Neurostim Blend

This is the first of the three proprietary blends in AD Shredabull Untamed. It’s designed to boost your mental performance so you can stick to your weight loss goals. It contains the following ingredients in unknown amounts:

  • Caffeine Anhydrous – a well known stimulant that can increase your focus and energy. You don’t want to take too much of it though, as there’s a thin line between reaping its benefits and suffering from its adverse side effects. Again, we have no idea how much of it is in Shredabull. It could be as much as 494mg, a dose that is potentially hazardous.
  • 2-aminoisoheptane – This is a chemical similar to the unsafe stimulant DMAA. Its aggressive properties aren’t to be messed with, let alone combining it with other stimulants like caffeine. The worst part is, we don’t even know how much of it there is in this fat burner.
  • N-Acetyl L-Tyrosine – Tyrosine is an amino acid that your brain uses to make dopamine and other neurotransmitters. It helps you stay mentally sharp under stress.

4. Incinerate Thermo Complex

This is the second of the three proprietary blends, and the main fat burning blend in Shredabull. Its ingredients include:

  • White Willow Bark Extract – We don’t currently rate this ingredient as one of the very best ones for fat loss. It’s generally not being used in the top fat burners because it lacks evidence that proves it works.
  • Higenamine Hydrochloride – This is a chemical found in some plants. It’s suggested to boost athletic performance. However, it’s on the WADA banned list. It also doesn’t help you burn fat.
  • Cayenne Extract – Now, this is an ingredient definitely worth mentioning. Cayenne is especially effective at triggering thermogenesis, a reaction of your body to an increase in core temperature leading to faster caloric expenditure. It’s sad we can’t see its dose in Shredabull and are thus unable to assess its effectiveness.
  • GBB (gamma butyrobetaine ethyl ester hydrochloride) – GBB is sometimes used in fat burner supplements, even though it doesn’t have much evidence going for it. It’s a mediocre ingredient at best.
  • Yohimbe – Yohimbe is a dangerous stimulant banned in countries like Canada and the UK. It can aggravate your heart health and cause a slew of issues, so we recommend staying away from it.

5. Thyrocharge Complex

This is the third and final proprietary blend of AD Shredabull Untamed. It’s designed, as the name suggests, to support your thyroid function. It consists of these ingredients:

  • Bovine Thyroid – This is essentially a thyroid gland of an animal, extracted and dried into a powder. Some studies show it might help support your thyroid function. This can actually be beneficial for weight loss as thyroid heavily influences our metabolism.
  • Guggul Lipid PE Extract – This comes from the Guggul tree. Its active compounds, Guggulsterones, have been studied for their purported ability to elevate thyroid function. However, the results are lackluster according to Examine.

6. BioPerine Black Pepper Extract

BioPerine is a patented, branded form of black pepper extract.

It contains the active compound piperine which, while doesn’t burn fat, helps your body absorb other ingredients better.

While this would be a good thing in many cases, it’s not in this one – stimulants like Yohimbine and caffeine don’t need potentiating!

Our Thoughts on the Ingredient Profile

It’s a seriously flawed formula. AD Shredabull Untamed has no appetite suppressants (e.g. Glucomannan), it’s using a number of dangerous ingredients that should be replaced with something safer and more effective, such as green tea extract and GTF-chromium.

How to Take AD Shredabull Untamed

Each bottle of Project AD Shredabull Untamed contains 50 caps. The dosage directions are to take 1 capsule per day. You can take it with or without a meal.

Some users wonder when is the best time to take Shredabull Untamed. The answer is – in the morning. Stimulants such as Yohimbine shouldn’t be taken too late as they elevate your blood pressure and heart rate, and also cause insomnia for most people.

Does AD Shredabull Untamed Have Side Effects?

Is Shredabull Untamed a dangerous fat burner?

It depends on whether you can tolerate it or not. Most people won’t. There’s just too many stimulants in AD Shredabull Untamed, many of them shown to be unsafe, and even completely banned in some cases.

Combining yohimbine and caffeine can lead to serious issues, add to that other stimulants in this product and you have a real recipe for disaster.

As a result, AD Shredabull Untamed’s potential side effects include:

  • Heart palpitations
  • Insomnia
  • Elevated blood pressure
  • Nausea
  • Headaches
  • Sweating
  • Panic episodes

How Long Does Shredabull Take to Work?

Shredabull starts working relatively quickly, within 30-45 minutes of ingestion. This is due to its stimulants which have potent short-lived effects, though they’re often accompanied by the infamous crash after a few hours.

Where to Buy AD Shredabull Untamed?

AD Shredabull Untamed can be bought on a number of websites online, however, it’s not currently officially available on Amazon. We’ve seen a few batches of the product available on eBay, though.

It ships worldwide, including to the UK, USA, and Australia.

Now onto the real bummer – the price. As it costs $48.99 per bottle, and doesn’t offer much in terms of benefits, AND is potentially unsafe, we think it’s not the best value for money overall, and should be avoided unless you’re highly experienced with these types of fat burners.

Project AD Shredabull Untamed Review Summary:

Shredabull Untamed didn’t work as we expected it to. It contains two decent ingredients – cayenne pepper and caffeine – but even these don’t have their dosages shown on the label so we don’t know if they’re effective.

The rest of the formula is completely unsafe with too many stimulants in it, along with a few completely pointless ingredients that should be replaced with something that will actually help you burn fat or suppress appetite (or both!).
